推荐答案

我假设 getUid() id 与电子邮件紧密相关，或者！?

I was assuming the getUid() id was tight to the E-Mail right, or!?

不是源自"意义上的绑定".关联"意义上的绑定".

Not "tied" in the sense of "derived from". "Tied" in the sense of "associated with".

请记住，电子邮件可以更改.发生这种情况时，当然 id 会保持原样.

Remember that the email can be changed. When that happens, of course the id is left as is.

您可以通过创建新用户、检查 ID、更改电子邮件并检查 ID 未更改，然后删除用户并使用相同电子邮件创建新用户并检查已分配新 ID.

You can easily test this in the Firebase console by creating a new user, checking the ID, changing the email and checking that the ID does not change, then deleting the user and creating a new user with the same email and checking that a new ID has been assigned.
